Subject: [PATCH] perf/evlist: show branch_sample_type bits
Date: Wed, 5 Aug 2015 17:59:15 +0200 [thread overview]
Message-ID: <20150805155915.GA5912@thinkpad> (raw)
This patchs improves perf evlist by adding the
dump of the branch_sample_bits. This is part
of perf_event_attr and is important to know
when sampling branches.
Patch is relative to tip.git
